Displays an image in an X window.

<P><STRONG>Functional Details</STRONG>
<P>
Displays image
<TT><STRONG>
i
</STRONG></TT>
in an X window on the display specified by
<TT><STRONG>xdisplay</STRONG></TT>,
with the title specified by
<TT><STRONG>title</STRONG></TT>. <TT><STRONG>xdisplay</STRONG></TT>
is used as the X display string when opening the window.  The window
associated with
<TT><STRONG>
xdisplay
</STRONG></TT>
is maintained for subsequent calls to
<TT><STRONG>
DXDisplayX
</STRONG></TT>
until the user closes it, after which a new window is created.
<P>
These routines can utilize 8-bit pseudo color X visuals, 12-bit
Direct Color and True Color visuals, and 24-bit Direct Color or
True Color visuals.
<P>
<TT><STRONG>
DXDisplayX
</STRONG></TT>
tries to create a window with the default visual, and if it is not of
an appropriate type, tries to create
an 8-bit, then 12-bit, then 24-bit visual.
The other routines try to create the appropriate depth window
first (for example, <TT><STRONG>DXDisplayX8</STRONG></TT> tries
to create an 8-bit window, then tries the default
window depth.
